Description
Technical field
The invention belongs to technical field of security and protection, relate to video monitoring, especially relate to a kind of video monitoring intellectual analysis search method and system thereof.
Background technology
Further develop along with socioeconomic, China wants quality, wants police strength, wants fighting capacity to become the theme of current public security department to science and technology for a large amount of man power and material of criminal investigation aspect input.Along with going deep into of safe city system and society's monitoring Large scale construction, solved the problem that the urban pavement video gathers and preserves reliably, accumulated the first-hand on-site supervision image document of a large amount of preciousnesses, for providing strong support in investigation, utilizing monitor video to search clue to solve the case has become means the most frequently used in criminal investigation and case detection, has hit dramatically the criminal offence of illegal one's share of expenses for a joint undertaking.Yet present stage, also there were problems in the safe city supervisory system:
1, in the face of rugged surroundings, supervisory system night dark low light cross bright situation hypograph quality according to, dense fog sand and dust inclement weather or local light and greatly reduce, cause the poor camera acquisition of video image quality to poor image quality, upper giant-screen is of poor quality, Video Document is of poor quality, the policeman in charge of the case can't therefrom obtain useful information, cause the clear up a criminal case difficulty, inefficiency.
2, video monitoring ubiquity camera position is unreasonable present stage, the shortcomings such as effective information is few, often need to spend a large amount of manpowers, time and check the magnanimity Video Document in case evidence obtaining and analytic process, seriously restricted its detection efficient, also there is the inevitably artificial erroneous judgement etc. of failing to judge in the retrieval evidence obtaining work of Traditional Man, and needs solution badly therefore public security video in the actual combat that utilizes the monitoring video investigation is examined the problem of inefficiency.
3, present stage is in most cases to dispatch the associated monitoring data by criminal investigation group to the application personnel of relevant department after the incident, carrying out artificial semi-automatic search judges again, reason due to site environment, the image of taking is unsatisfactory, can't see details clearly, be not easy to public security department or vehicle supervision department and monitor processing, in the situation that the low public security police of video quality is substantially at a loss what to do, in the face of the examination one by one that the video monitoring data of magnanimity also can only waste time and energy, the criminal investigation people's police feel this to be sorely distressed.
4, watch for a long time the low video of quality may increase the weight of the burden of people's eyes, easily produce visual fatigue, even can have a dizzy spell, the contrast of scene image and color all can be changed or degenerate under rugged surroundings, the many features that contain in image all are capped or are fuzzy, and what obtain is degraded image.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of video automatic concentration method [application number: 201110208090.X] based on video surveillance network, it is to obtain the first video source and the second video source and to moving Object Segmentation and tracking, extract background image and video surveillance network movement locus from two video cameras with overlapping region; Generate panoramic picture based on video surveillance network according to background image, obtain two video cameras separately corresponding to the projection matrix of panoramic picture and the real-time update panoramic picture based on the video surveillance network background; Utilize the projection matrix of two video camera panoramic pictures, track is projected to the panoramic picture space obtain projected footprint; Adopt the figure coupling, based on the projected footprint coupling of random walk thought to the video source of two video cameras, obtain matching track pair, the matching track of overlapping region is selected and merged, obtain complete large scene track; The large scene track was rearranged by the time, on panoramic picture, complete large scene track is represented, obtain based on the video of panoramic picture concentrated." computer engineering and application " the 25th phase in 2008 discloses the video retrieval method (author: Xue Liqin that a kind of based on motion is analyzed; Zhang Xiujuan), introduce people from different application purposes, proposed the method for motion analysis in many different videos.Sum up, these analytical approachs can be divided into four classes: light stream estimation algorithm, motion vector estimation algorithm, based on histogrammic statistical analysis technique, parameterized global motion analytic approach.
Although such scheme has improved video analysis efficient to a certain extent, be difficult to obtain easily needed information in video but still exist, be only the length that has shortened whole video, and any processing is not made in association between the effect of video, details, video etc.
